By early next week, we might be talking about a Category 5 hurricane, but widespread flooding is going to be the most impactful threat from Melissa. Here's how bad it could get in Haiti and Jamaica.

An intensifying Melissa will bring destructive flooding to Jamaica, southern Haiti and the Dominican Republic before tracking toward Cuba, the Turks and Caicos Islands and the Bahamas next week.

The National Hurricane Center in Miami warned of "life-threatening and catastrophic flash flooding and landslides" throughout Hispaniola.

Tropical Storm Melissa grounded to a halt over the central Caribbean about 150 miles south of Jamaica and Haiti early Friday.
